[jboss-user] [JBossWS] - Unable to create JavaBean of type org.w3c.dom.Element

[amit_sri]

Hi,

I have developed a webservice with JWSDP-2.0 (jax-rpc wscompile tool) deployed it on JBoss 4.0.2 AS. I have taken bottom-up approach starting with Service interface which takes org.w3c.dom.Element and return the same.  
Everything happened smoothly until I invoked the deployed WS using client (generated by wscompile tool plz see stacktrace below) .  If anyone has faced this before please provide me some insight. 

Thanks in advance,
Amit Srivastava..

I am getting following exceptions-
